If sine ⁡theta equals negative 8/17 and the terminal side of theta lies in quadrant IV, find cosine ⁡ theta .

Lelechka [254]

$\sin^2\theta+\cos^2\theta=1\implies \cos\theta=\pm\sqrt{1-\sin^2\theta}$

Since $\sin\theta=-\dfrac8{17}$ , it follows that

$\cos\theta=\pm\sqrt{1-\dfrac{64}{289}}=\pm\sqrt{\dfrac{225}{289}}=\pm\dfrac{15}{17}$

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so

$\cos\theta=\dfrac{15}{17}$

A cheetah can travel up to 29 meters per second.what is the cheetahs speed to the nearest tenth in miles per hour? (1 mile=1690

Ray Of Light [21]

64.87=64.9 mph
I think I'm not so familiar with meters.
1 mps (meters per second) = about 2.23 mph (miles per hour)
Therefore, 29 x 2.23=64.8712
Rounded to the nearest tenth and it is 64.9.

Answer:

x = 7,y = 8

Step-by-step explanation:

(20 + x + y )/ 5 = x

4x = 20 + y

x ≥ 6

y ≥ 6

if x = 6, y = 4 No

if x = 7, y = 8 Yes!
